摘要
采用简单的一步水热法成功制备了具有3D分级结构的CoAl2O4,利用X射线衍射、扫描电子显微镜、紫外-可见漫反射吸收光谱表征方法考察了 CoAl2O4的结构形貌、成分和物化性质对其光降解性能的影响.构建CoAl2O4-可见光(Vis)-过硫酸钾(PS)耦合体系(CoAl2O4/PS/Vis),处理废水中的亚甲基蓝(MB)污染物.由于CoAl2O4独特的3D分级结构及光降解技术和PS高级氧化技术之间协同效应的存在,可见光照射100min,CoAl2O4/PS/Vis耦合体系对模拟废水中MB的去除率达94.8％,并阐明了 CoAl2O4/PS/Vis反应体系光催化性能增强的机理.
Abstract
The 3D hierarchical CoAl2O4 was prepared successfully by one-step the hydrothermal method.The influence for morphology,composition and physicochemical properties on photocatalytic performance was investigated by XRD,SEM and UV-Vis.The CoAl2O4/PS/Vis coupled system was constructed to remove the MB containing the wastewater.Due to the unique 3D characteristic as well as synergistic effect between CoAl2O4 and PS,the removal ratio of CoAl2O4/PS/Vis system for MB reached to 94.8％under visible irradiation 100min.The enhanced mechanism for mineralization MB of CoAl2O4/PS/Vis system was discussed detailed.
